Password Entropy Calculator

Password Entropy Calculator MCP Connector for Claude

A+

Calculate password entropy, identify pattern risks, and verify security policy compliance.

3 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides a specialized toolkit for assessing the mathematical strength of passwords. It uses Shannon entropy to calculate bits of unpredictability and estimates brute-force crack time based on configurable guesses per second. Beyond raw entropy, it identifies human-predictable vulnerabilities like keyboard walks, sequential characters, and character repetitions using audit_pattern_risks. Additionally, you can enforce organizational security standards by checking if a password meets specific length and character class requirements with verify_policy_compliance. Use evaluate_password_strength to get a deep dive into the entropy bits and search space of any given string.

How strong is the password 'P@ssw0rd123'?

The password 'P@ssw0rd123' has an entropy of approximately 45.2 bits, which is considered a Medium strength level.

Check if 'abc12' meets a policy of 8 characters and requiring at least one digit.

The password 'abc12' is not compliant because it fails the minimum length requirement of 8 characters.

Are there any dangerous patterns in 'qwertyuiop'?

Yes, the password 'qwertyuiop' contains a keyboard walk pattern.

Strength is determined using Shannon entropy, which considers the length of the password and the size of the character pool (uppercase, lowercase, digits, and symbols) to calculate bits of unpredictability.
